Dual-output buffer for DDR SDRAM modules
Fairchild Semiconductor has introduced a dual-output registered buffer for 184-pin, 2.5V PC200/PC266, 72bit-wide registered double data rate (DDR) SDRAM modules.
"This novel product is the result of a joint technology development programme between the analogue and optoelectronics groups of Fairchild Semiconductor", according to Steve Sherman, Fairchild Semiconductor Senior Vice President, and General Manager of the Optoelectronics Group.
"The resulting optically isolated error amplifier is an ideal single component solution for power conversion applications".
The optocoupler is a gallium arsenide (GaAs) light-emitting diode optically coupled to a silicon phototransistor, and provides 2.5kV RMS isolation.
The reference voltage is 1.24V with 11% tolerance, the current transfer ratio (CTR) range is 100 to 200%, and the operating temperature range is -40 to +85C.
The FOD2712 has CSA and UL safety agency certifications, and VDE and BSI safety agency certifications have been applied for and are pending.
